Engine Oil Filter 1R-1807 Spin-On for Caterpillar Excavators & Industrial Engines
1R-1807 oil filter for Caterpillar excavators and 3300/3400 series engines. OEM cross-reference verified. Bulk orders from IXIN Filter.
Description
This 1R-1807 oil filter is an advanced-efficiency spin-on engine oil filter engineered as a direct replacement for the Caterpillar 1R-1807. It shares the same dimensions and fitment as the 1R-0739 part number and is Caterpillar’s specified service filter across a wide range of 3300-series industrial engines and related excavator, motor grader, and generator set applications.
Product Overview
The 1R-1807 oil filter uses cellulose-pack filter media designed to capture finer particulate contamination than standard cellulose media, while maintaining high dirt-holding capacity. As explained in industry filter media guides, cellulose media traps particles within its fiber matrix as fluid passes through, making it a practical and widely used option across engine, fuel, oil, and hydraulic filtration. As a full-flow spin-on filter, it’s built for straightforward installation and reliable sealing on a 1-1/8-16 UNF-2B mount. Each unit is dimensionally verified against OEM measurements and tested for filtration performance before shipment — not just matched by part number.

This filter shares the same fitment and specifications as the Caterpillar 1R-0739 part number. Always confirm your engine’s serial number range against the OEM cross-reference before ordering, as filtration specifications can vary across production years and applications within the same engine family. For modern C13/C15/C15 ACERT on-highway engines, the specified service filter is generally the 1R-1808, not this part — verify your engine model before ordering.

Frequently Asked Questions
Is the 1R-1807 the same as the 1R-0739? Yes. The 1R-1807 and 1R-0739 share the same fitment, dimensions, and function — both are commonly cross-referenced to each other in CAT’s filter documentation.
What engines use the 1R-1807 oil filter? It’s Caterpillar’s specified service filter for a range of 3300 and 3400-series industrial, marine, and generator set engines, in addition to fitting several excavator and motor grader models.
Does this fit modern C13/C15 on-highway engines? Generally no — for modern C13, C15, and C15 ACERT on-highway applications, the specified service filter is typically the 1R-1808, not the 1R-1807. Confirm your engine model and serial number before ordering.
Do you offer samples before a bulk order? Yes. We recommend requesting a sample for independent testing before committing to a bulk order, especially for first-time buyers.
